Turtle is a species with a high survival rate among freshwater aquaculture species. However, in recent years, turtle farming has also become more difficult to raise. Sometimes the survival rate is only 50% to 60%. The main reason is the continuous deterioration of the breeding environment and the breeding density. Increasing.

According to the traditional breeding experience, farmers always mistakenly believe that since soft-shelled turtles are amphibians and reptiles, no matter how lack of oxygen in the water body, it will not cause harm to soft-shelled turtles. Therefore, turtle breeding ponds do not need oxygenation.

Years of practical experience in production tell us that farmers have taken oxygen-enhancing measures in the process of turtle breeding, and the breeding effect has improved significantly and economic benefits have improved significantly. From the comparison, we can conclude that adopting oxygen-enhancing measures to breed soft-shelled turtles generally has the following advantages.

1. The water quality of the turtle ponds where the oxygenation measures were taken was high in dissolved oxygen, low in ammonia nitrogen and nitrite nitrogen, stable in feeding, less disease and fast in growth.

2. Although the input cost of electricity and aerators was increased during the breeding process, the frequency of disinfection and medication was reduced, the incidence of diseases was reduced, and the survival rate of soft-shelled turtles was improved.

3. The commercial soft-shelled turtle raised in that year can gain an average weight of 50-80, the total output is increased by about 10%, and the input-output ratio is significantly improved.
